INVENTOR WILL/Am /foLAM/QN v ATTORNEY Paieniea May 23, 17933 UNITEDSTATES PATENT oFFicE p Application `tiled. Hay 31,

rI`his application relates to applicators for liquid cosmetics and thelike.

It is ian object of this invention to provide apparatus for theapplication to the skin surfaces or the like of cosmetics or materialshaving a predetermined medical effeet, such as the application ofcoloring matter to the lips of a person, as is customarily done in theapplication of lip-stick, or in' the use of solution of camphor orsimilar substances. In conjunction with such apparatus would be used afluid carr ing the desired materials, such fluid-utilizing water or somesimilar liquid as the carrying medium so that there is producedalfinalsolution, emulsion or similar fluid which will react normally inaccordance with the ordinary laws of surface tension applicable toliquids which wet a surface.

The apparatus is constructed so that one or more capillary passages areprovided' through which the iiuid may be fed to an applicator tip whichis used to spread the fluid over the surface to be coated or moistened.rlhe tip, in suitable cases, may vhave a slit or similarly sharplydefined opening, or may have a pad of felt, s onge rubber or similarmaterial through willich the iiuid might be fed for spreading in thedesired manner.

By forming an enlargement intermediately of the capillary passage orpassa es, in

any manner, provision may be made or the storage of fluid at anypredetermined distance from the point of application, or with relationto a main storage chamber, which.

may be provided auxiliary to the applicator ti In a proper case, meansmay be provi ed for adjusting the capacity of this 0 storage chamber inaccordance with the viscosity of the li uid handled, or to adjust thecharge of liqui to be fed to any particular single operation. l

It is an additional object of this invention to vrovide an a plicator ofthe type hereina ove set fort and in which a primary reservoir islocated adjacent the end of the applicator, wherein a device isassembled within the reservoir and is operable to limit 5 the flow fromthe end of the applicator' 1980. Serial No. 457,802.

when the force of gravity is added to the capillary force actin@ to moveliquid through the passages uch device may also operate to trap liquidwithin the reservoir When the passage is positioned upright and thetendency of gravity would be to draw the liquid downwardly through saidpassages and away from the applicator tip.

It is a further object of this invention to provide an applicator nozzlehaving two or more capillary passages leading therethrough substantiallyin parallel relation, the capillarity of at least one passage being lessthan that of the other so that, as the applicator tip is applied tothe'surfaceto be moistened, the passage capable of exerting only thelesser capillary force will" become an air vent for the reservoir withwhich it is assembled. The reduction in capillary effect in any onepassage maybe accom- 7o plished in any suitable manner, as by variationof the diameters of the passages. A preferred method, however, is toincrease the capillary action in one passage by inserting a very finewire theremto.

It is an object ofthe invention to provide a'n a plicator of the typeherein described which will be capable of feeding fluid for coating ormoistening a surface which is disposed in any plane relative to theapplicaso tor, thatis, a surface above, as well as a surface below theapplicator, and one vertically disposed, as well as one horizontallydisposed. For this purpose, the property of certain fluids, known assurface tension, is utilized to effect the feeding of such fluidupwardly, or in any other direction, for attaining the desired coatingor moisteningv of said surface.

The applicator discharge end may, for the 'purposes of-this invention,be disposed in a vertical, as well as a horizontal, or like plane. Inany case, suitable vents are provided to assure the'necessary flow of liuid to the final discharge orifice or like fee ing means. Noparticularmethod of venting the storage chamber or like supply source ofliquid is lintended to form a specific part of the generic inventionherein involved.; however, certain specied methods of' vent- 100 inghave been designed which cooperate with the generic invention to edectcombinations claimed by me as specific inventions. The invention may beincorporated into a suitable device capable of being carried in a purseor may, in any other suitable manner, be assembled for use.

@ther objects of this invention will be apparent trom the drawin andtrom the description thereof, or wil be specitically indicated therein.

Fig. 9 is a vertical sectional view through a tui-ther modified formofthe invention.

ln the particular construction ot Figs. l and 2, the invention is seento have been embodied into a container l0, which may be made of anysuitable material for 'retaining liquids therein, and which may lenditself readily to formation into such ornamental shapes and the like:tor commercial purposes as may be desired. Preferably, the container isot sinall diameter or cross-section, and consists ot a tube l2, to whichmay be secured, in any desired or well-known manner, a bottom ll, suchbottom being made nordsee readily removable .tor refilling or similarpur oses.

'll e other end ot tube l2 may have assembled therewith a nozzle cap 16,removably retained upon the tube, as by means of screw threading or thelike. lhrough the cap is formed abore 18, within which the body 20 ofthe applicator 22 is received and retained.

The applicator, in a referred, but not a necessary, form, is ma e up ota pair oil mated sections 2t and 26. rl"he a plicator could be made inany other suita le manner, as by drilling, or otherwise working, a solidpiece ot metal or the like. The mated sections may be formed out otbakelite, hard rubber or similar substances which the liquid to be usedtherewith will wet, the mating surfaces et the sections beingsubstantially dat throughout. ln portion 28 of the applicator, thesurfaces are intended to conform accuratel to each other so as toprovide a li uid-tight dt when the sections are united, t e surfaceshaving no spacing therebetween except at cut-out portions in each ot thesections which are mated to produce a duct 30.'

At the external portion 32 et the applicator, adjacent the nozzle cap,the dat sur- 'laces ot the opposed sections are separated an appreciableextent to provide a passage 38, the surfaces then 'either continuing atthe same degree ot separation, or converging to a tine line opening t0at the exterior.

surface ot the applicator. rlhe junction edges or the sectionscontiguous to passage 38 are sealed together in any well-linown mannerto provide a water-tight, non-lealiing connection. At the point etorigination of the passage, the duct 30 is completely or substantiallylost thereinto. llllie two surfaces ot the mated sections at asse-ge 38are separated to such degree t at but a capillary passage is producedtherebetween, so that liquid deposited at the beginning or the passagewill be ted, due to the eilect et surface tension, to the outer end ortip of the applicator. rl`he principal result ot the invention hereindoes not, however, require the specific construction hereinabove setforth, as arrangement ot one or more capillary pas'- sages of anyparticular constructions may be utilized tor' the purpose herein setforth. Liquid ted to the outer end or tip or the applicator by an means,that is, either by capillary torce in the passage or by thegravitational or lilie torce exerted by the ody oil the liquid withinthe chamber oil container l0, will meisten the tip so that, when the tipend is moved across any surtace to be moistened, such as the lips et aperson, when the applicator is used tor' liti end moves onward, thejoinder of the liquid film and the liquid in the applicator will cause amovement of liquid through the duct orcapillary passages of theapplicator, the liquid therein moving tol compensate .for that liquidwhich has been removed, due to the effect of the forces of surfacetension.

To clarify still further, theunion of the body of liquid within theapplicator passages or ducts with the wetted surface results in theapplication of a force upon the bodyr of liquid adjacent the tipopening,

, drawing it out therefrom as the liquid in the applicator end seeks tojoin the liquid wetting the4 surface, due to the fact that a liquidtends to assume the smallest possible surface underl the circumstances.This force externally o f the applicator will be greater than thesimilar force applied to the liquid within the tubes or passages by thewalls thereof, because of the greater extent of the external surface,and the liquid within the passa es will tend to move toward the liquiddeposited externally, In other words, as the applicator continues tomove over the surface to be coated or wetted, the flow of liquid fromthe passages will continue so long as there is a liquid connectionbetween the external liquid and the liquid Within the tube, or so longas the latter holds out.

Where the tube is held vertically, so that liquid would flow down intothe capillary passages under the yforce of gravity, the sup'- ply goingto the surface to be moistened will he limited only by the contents ofthe con?,`

tainer.4 However, where the tube is held vertically upward and the forceof gravity is not operative to lift the body yof liquid from thecontainer into the capillary passages of the applicator, the extent ofapplication possible is limited by the quantity of liquid having directliquid connection with the liquid at the tip end of the applicator, ascan be readily understood.

lln order-to facilitate the capillary feeding of liquid between the twocomplementary fiat surfaces, hair line depressions 42 are provided toconstitute a plurality of 26 are mated. In this manner, .the necessityfor having the convergence of, or the close approach of the surfaces'toeach other with any considerable accurateness is avoided. V

In order to provide a quantit of liquid for use at the applicator tip,in w ateverposition it may be used, it is found desirable vto have asecondary storage chamber of small capacity adjacent the outlet from theapplicator. For this purpose, a suitable enlargement 44 of the duct 30is formed within the body of the applicator in closel adjacency tothetip end and substantially at the commencement ofthe final capillarypassages. In this manner, liquid may be .tip

fed to the enlargement throu h the duct 30 and be retained therein. A tin film of liquid will form in the passage 38 and, in most cases, willbe liquidly connected with the liquid in the enlargement; the inabilityof atmospheric pressure tol breakl down this film of liquid will act asa seal, under normal circumstances, to retain the liquid, so fed,trapped in the enlargement. Then, when it is desired to make use of theli uid thus stored, the applicator tip is applie in the customarymanner, and liquid will flow from the enlargement into the capillarypassages and then out thereof in the manner hereinabove set forth.

It may be desired to rotect the applicator against excessive ischargewhen apparatus of the type hereinabove set forth is used with theapplicator tip ,pointed substantially downward and gravitational forceis exerted by the body of liquid within the chamber of the containerupon the of liquid from the enlargement when the is pointed verticallyupward, and against the possibility of breaking the liquid Vseal at thetip, in which case the liquid in the enlargement may flow down the ductand into the reservoir of the container l0,

an additional seat 50 may be provided at the junction of the'duct 30with ,the enlargement. When the applicator is positioned with the tipportion thereof pointed vertically or substantially so upwardly, theball 46 will coact with the seat 50 toclosey off communication betweenthe enlargement and the duct. y

Some suitable means must be provided for venting the chamber of thecontainer l0. For this purpose, the nozzle cap 16 is provided with oneor more air vent passages 52 which extend therethrough and provide opencommunication between the exterior of the container and the interiorthereof.,

Preferably, these passages taper inwardly so that the liquid withinthecontainer, when the container is positioned with the applicator tipdownwardly, will be restrained against flowing down through the airvents, while air will be permitted free access to the container at anyother time. As appears at 54, I have found the end of a hypodermicneedle', with the tip thereof ositioned within the chamber and the ot erend thereof externally of the container 10 to serve-elliciently thepurposes intended. 1

ln order that the container and the attached applicator tip may becarried in such means as a pocketbook or the like, a cap 56 is provided,and may have means for screwL threadedly engaging the outer surface ofthe nozzle cap to close the cap down a ainst the nozzle cap and also tobring a ruber or like cushion 58 retained within the endl of the ca downupon theend of the a plicator tip,thus to seal the latter. rlhe cu ionwill also serve to maintain a film of liquid at the tip, after oncemoistened, so that the tip will be prepared for instant use, upon theremoval of the ca Preferably, the shoulder 66 of the nozz e cap and theface 62 of the cap are formed to cooperate in such manner that, when theca has been brought down against the nozz e cap, the shoulder 66 willtightly abut the face 62 and substantially seal od the ends of the airvent passages.

ln Fig. 3 is shown a modied form of the applicator tip which is adaptedfor use either in connection with a primary reservoir such as providedby a container 16, or in anyother similar relation. 'lhe a plicator 6ftin this modification may be ma e of material similar to that used forapplicator 22; also, the a plicator may be made up in substantially t esame marier, that is, by the use of two sections, brought into abuttingand mating relation, althouh in either case, it is not essential thatsuc construction be followed to attain the desired form. lln the case ofapplicator 6d, a duct 66 is formed by the mated sections, the passage 1leading to a reservoir chamber 68 from such an article will not jar theplug out o a set-up position. ln order to ermit thel feeding of liquidfrom the cham r of the container with which such applicator is.

. assembled, one or more capillary or like ducts 76 are provided inthewalls of the duct 66 or in the face of the plug, and extendsubstantially the entire length thereof. lln

this manner, the plug is by-passe'd and liquid supply for the reservoirchamber set up.,

A ball 78 may be retained by the plug within the reservoir chamber tocoact with -a suitable seat 86 at the entrance to the Y' Y capillarylpassages 76, as set forth above for the ball d6, The" 'capillarity ofducts" 76 will substantially prevent any back-flow the plug in the.

faces 9a forming the capilla terence' y therethrough, so thatno othermeans is necessary to check such dow.

For venting apparatus of the character set forth above, and as shown inFig. 3, itis possible to use passages similar to the air vent passages52 in the nozzle cap or to provide a vent passage 82 which may be formedlengthwise through the applicator body, opening at the external face 84of the applicator and into the chamber of the container with which theapplicator is assembled. 'lhe passage 82 maybe shaped in a mannersimilar to the passages 52, that is, converging inwardly, to prevent, toa substantial degree, the. outdow of li uid therethrough at undesirabletimes. By t is means, liquid will be permitted movement up through thecapillary passages 76 to the tip end while air wil move down the ventpassage to the chamber of the container to compensate for the reductionof pressure therein as liquid is withdrawn.

ln liigs. l and 5, a further modification of the invention is disclosedin which the capillary passages, instead of opening at the extreme tipof the applicator, open along a surface 86 at the side of theapplicator. llt is to be understood, in this connection, that theparticular location'of the applicator tip or surface is of no s ecicimport since, as in this illustration, 1t may open at the side of theapplicator, as well as at the extreme end. lin this construction, theapplicator end is not formed lwith the line opening, as are themodifications previously discussed; a substantial opening is providedwithin which is seated a pad 88 of felt, sponge rubber or similarmaterial which, in itself, exhibits capillary functions. Liquid broughtinto contact with the pad will thus wet the same and be conducted to theouter surface thereof to be applied to any surface with which the pad 1sbrought in contact.

A reservoir 96 may be provided in connection with an applicator of thetype herein set forth, and an air vent 92 open through the walls of theapplicator from said reservoir to the atmosphere; Preferably, such Iventwould be tapered inwardly, in the same manner, and for like purposes, aspreviously set forth.

A. further modihcation of the invention is disclosed in Fig. 6, in whichcase the flat surl passages are dented, as at 96, in any suita lemanner, to

4provide small pockets or recemes for receiving and retainii small suplies of liquid, as the same is f through t e passages. Thus, as liquidpasses throu h the capillar p sage, these pockets wil provide smallreservoirefor holding reserve` suppliesV of liquid; should the @dect ofcapillarity be lost at a lower point, these supplies will becomeeffective and will be fed to the outer can ill@

otherwise available.

In Figs. 7 and 8, a method of conducting air to the container and ofproviding for thc capillary action of the necessary passages is shown.In this case, the surfaces of the mated members 98 and 100 are notcomplementary but are substantially convexed so that but a small portionof one is contactedwith a small portion of the other. The other portionsof the surfaces are free of each and substantially diverge away fromeach other. Thus at some point, the effect of the force of suriacetension will be broken between the two surfaces and a free area thesurface can therefore be utilized for the purpose of conducting air tothe interior of the container.

ln Fig. 9, there is disclosed a inodiiication of the invention in whichthe applicator 102 has formed therein a pair ot capillary passages 10dand 106, leadin' upto the common tip 108. The tip end, ior the purposesoi the invention, is not made straight across the end but preferably isslightl curved so that, in use, the entire face wil not contact thesurface to be wetted. For the purposes oi the invention, one of thepassages is pref erably made capable ot exerting a lesser capillaryforce than the other, either byniaking the diameter thereof greater thanthat oil the other, or, as in the arrangement herein shown, by insertinga hns wire ll() inone of two passages of equal diameter. Thereby, theedect 'o'liquid upon the surface off the wire is added to the effect ofliquid upon the surface of the passa e and the torce in such passage isthere y increased over that of the other passage. When application takesplace, liquid will normally travel down the passage havin-g the wireil() therein, while air will flow up the other passage or passages otlesser capillary force.

As many changes could be made in the above yconstructions and manyapparently widely diiierent embodiments of the invention designedwithout departing from the scopennd spirit of the invention, as definedin the'accornpanying claims, it is intended that all matter contained inthe above`descriptlonor shown in the drawing shall be interpreted asillustrative merely of an operative embodiment of the invention and notin a limiting sense.

It will be understood that de ressions or recesses such as shown at 94an 96 may be located, if desired, within the one or more of thecapillary passages. y

' It will also be understood, of course, that where a plurality ofcapillary passages orl tubes are provided, as for example in Fig.`

9, these passages may vary in cross sectional area and one or more ofsuch capillary assages may be sub-divided lon itudinal y so as toprovide a multiplicity 0% smaller capillary grooves or channels withinone or more of the majorl passages. Where a lurality of capillarypassages are provi ed, these, of course, may vary in length. l e
